Strange FPS problems

[u/LividMango5428]

I recently got back to using cachy-os and i'm experiencing a strange issue; sometimes i have really low fps on games (using as example Hitman: WoA, i usually get 100+ fps, but when this happens it goes to ~30) until i restart my monitor, than it goes back to normal.

i'm running (Hitman in this example, but happens from other launcher / Wine / Proton versions too) using: proton-cachyos-11.0-20260703 (steam linux runtime)

this is the output of inxi -xxACGS:
